Phoenix police say one person was taken to a hospital in extremely critical condition following a crash Saturday evening near Jefferson and 24th streets that affected light-rail service.

Sgt. Tommy Thompson, a spokesman for the Phoenix Police Department, said a man was traveling in a vehicle eastbound at a high rate of speed when he lost control and collided with a pole on the light-rail tracks.

The light rail will be routing passengers around the area with buses, police said.

Jefferson and Washington streets will remain shut down while the crash continues to be investigated.
